With Prince William and Anya's level of knowledge and wisdom, it is not enough to imagine how powerful an asteroid with a diameter of 400 meters will release when it hits the earth at a high speed.

But when Han Xuan said that he could slightly realize the seriousness of the matter. When he learned that such an asteroid could destroy the entire London or New York, he showed a fear expression.

A few years ago, the large meteorite that accidentally fell on the snow-capped mountain ranch could already make the surrounding ground shake. Now the piece flying at high speed in the depths of the universe is much larger than it.

"Seventy-one percent of the earth's areas are covered by sea water, as well as the southern and Arctic continents and sparsely populated Africa, central Australia, Siberian plains and other areas.

If you fall in these places, there will not be too many casualties, and the impact will be eliminated in the short term.

From the perspective of probability, there should be no need to worry too much. We still have enough time to deal with it. When the asteroid slowly approaches, scientists can calculate and get the exact fall site.

According to the current situation, the most likely thing is that it will walk away from a very far away from the earth, or unfortunately pass by the earth through the gravity keyhole. If we are lucky, we can see the second moon."

The probability of impacting the earth is quite low. Even if it is successfully affected by the gravity keyhole outside the earth, it may deviate from the earth's orbit until the next cycle or other operational cycles. By then, it is likely that humans have the ability to withstand the impact of asteroids of this scale.

Han Xuan is not very vigilant about this, everything remains to be seen. In recent years, the earth is still safe.

He just finished shrugging and Prince William raised his own question: "But it may also fall in densely populated areas, isn't it?"

“Yes, that’s why the United States will launch an alarm to prepare for the rest of the world to respond to the crisis.

After I return to the United States, I will learn more about Apofil and let you know later.

I won’t talk about this anymore, just have dinner first, I’m a little hungry.

I like to see the night sky of these desert countries the most, which lacks water vapor and pollutants to block it, which is thrillingly beautiful.

Every summer, you can see similar scenes from my ranch…”

Hearing Han Xuan's words, Anya looked up and Fat Ding looked up.

The Milky Way is clearly revealed, and various stars form a large cluster of densely packed, appearing in strips, and other places are also covered with stars. The existence of near-Earth satellites can be seen with the naked eye. It is brighter than Venus and moves through the sky...

When it comes to satellites, we have to talk about Motorola's recent big moves.

It has been so popular in recent years, and it seems that it is about to ban major communication operators and seize half of the world's communication market.

All this starts with Motorola's "Iridium Plan" with a total investment of nearly $5 billion.

Since the late 1980s, Motorola's senior executives have had the idea of ​​dominating the communications operation industry and established Iridium in 1991, planning to launch a total of 66 near-Earth satellites into outer space, with an estimated service life of five years, trying to establish the best satellite communication service channel.

In fact, just like in the previous life, it really did this.

In the past two years from 1996 to the present, Motorola has spent nearly 5 billion US dollars to send 66 satellites to the sky, successfully established a global satellite communication system, and in order to win over operators from various countries, it also borrowed 3 billion US dollars from banks as a follow-up investment, resulting in the heavy burden of the Iridium project being born.

Han Xuan has been paying close attention to this "spectacular" plan. Last month, US Vice President Mr. Gore just became the first user of the Iridium satellite communication system and successfully used it to call his wife. The live screen was seen by countless families through live broadcast.

A mobile communication network composed of sixty-six low-orbit satellites aims to break through the limitations of ground mobile communications and realize the globalization of personal communications. As a modern person who has experienced the future, it is difficult for Han Xuan to understand Motorola's behavior.

In fact, in the early 1990s, the entire mobile communication system was still very imperfect, and it was in an era of transition from analog signals to digital signals. People's demand for real-time communication is becoming increasingly strong. Whoever can seize the initiative can successfully occupy the market. The Iridium project was born in that context.

The cost of forming a ground communication network covering the world is simply astronomical. Referring to the investment of hundreds of billions of yuan in the future, we can roughly know that Motorola believes that there is no company that has the ability to lay hundreds of thousands of base stations, so it began to turn its attention to the sky.

This idea was not wrong at the time, but fate played a joke on Motorola.

The development speed of digital signals is much faster than expected, almost every year. With the investment of funds, various technologies have made breakthrough progress, forcing Iridium to plan to go public early, resulting in the entire Iridium global satellite communication system, which is actually not stable.

When users use it, the disconnection rate is as high as about 10%, which is higher than that of ordinary mobile phones. In underdeveloped areas, the disconnection rate when using Blueberry mobile phones to communicate can be controlled within 6%, and the quality is commendable.

As expected, Iridium must have at least 500,000 customers to ensure profitability. During the preliminary investigation, the customers who intend to use it far exceeded this number, reaching about two million, which made Motorola tempted by the profit prospects and gritted the bullet to tinker with it.

In Han Xuan's view, this is a project that is destined to lose money. Except for some special industries, no customer would want to use an old antique sky-high mobile phone weighing up to 3,000 US dollars and having a call fee of up to 7 US dollars per minute. Motorola went bankrupt in his previous life, part of which was caused by the Iridium project.

At the end of last year, Iridium also came to Snow Mountain Group to try to cooperate with him and successfully convinced Anthony to executive officer, but the investment plan was decisively rejected by Han Xuan. This plan deviated from the development direction of later communication systems. Its early investment was too large, and the satellite's service life was only a few years. If it weren't for knowing it in advance, Han Xuan might really like it and become a tragic "taker".

Because major communication operators see the limitations of satellite life, they would rather spend a lot of money to build base stations on the ground than ride on Motorola's ready-made global satellite communication system.

Faced with the upcoming crisis of competitors, Han Xuan only wants to say three words: Hahaha!

With huge debts, the capital chain may be broken at any time. When people find out that the Iridium plan will not work, Motorola's stock price will inevitably fall sharply. In addition, the Blueberry Group encircles it, maybe it will fall into bankruptcy in advance in this life.
Chapter completed!
